Help - Tutorial:Adding support values (step 3)

The goal of this last step of the tutorial is to show a how hidden node data column can be used to still identify terminals by their lab IDs although the displayed node names might have changed. We assume that we already prepared the tree generated in the last two steps for publication or presentation (as shown in the beginning of the screen cast below) and later on decide to include more support values. This is still possible if we saved the lab IDs e.g. in a hidden node data column.

Note that the Applying name tables functions was removed from TreeGraph in version 2.0.50, because its functionality was included in the new Importing node/branch data function. (See there for details.) You can perform the steps in this tutorial using the new Importing node/branch data function instead.

Procedure

• The first thing we do in this step is preparing our tree to be published or presented. Therefor we replace the taxon lab IDs by real taxon names which shall be displayed italic. (See Applying name tables for details.) The important thing here is that we first copy the lab IDs to a hidden node data column before replacing them.

• By doing that TreeGraph 2 is still able to identify which lab ID belongs to which terminal node. We now decide to import additional support values from the file trnL_boot.tre. Since this file also identifies the terminals by their lab IDs and not their taxon names we select the previously created hidden node data column to identify the terminals in our document. (See Adding support values for details.)

• Finally we position the newly imported text labels and select an italic font to be able to differentiate the two groups of support values positioned above the branches.
